Cancelled Contract in collections

On 27 July 2021, I wrote a complaint regarding the delay in cancelling my contract. I had paid the quotation that Vodacom gave me but no confirmation of cancellation was sent to my phone. I got this message " Dear *****goa Shongoane your quotation has been processed ***. Use the order number *** when contacting Vodacom Customer Care on 082111 for further enquiries. That was finally cancelled on 31 July. Today I called Vodacom to query something different. I am told that my account is in collection. I don't know whether to laugh or cry. Like what is going on there? Do your departments talk to each other? Do your systems talk to each other? Come on guys this is really tiring and disappointing
